OBJECTIVE The aim of this study was to investigate the effect of apolipoprotein (apo)E4 allele on plasma LDL cholesterol response to calorie-restricted diet therapy in type 2 diabetic patients. RESEARCH DESIGN AND METHODS Twenty-four diabetic patients with the apoE3/3 genotype and 11 diabetic patients with the apoE4/3 genotype were recruited. Participants were hospitalized for calorie-restric...

BACKGROUND The apolipoprotein E (apoE) epsilon4 allele has been shown to be a risk factor for dementia, but it is not clear to what extent apoE affects overall cognitive function in non-demented elderly subjects, or how this risk may be modified by gene-environment interactions. OBJECTIVE To examine changes in cognitive function in elderly people as a function of the apoE epsilon4 phenotype. ...

INTRODUCTION Subspecies of apolipoproteins can be defined by fractionating apolipoproteins based on the presence and absence of coexisting apolipoproteins. METHODS We determined age- and sex-adjusted correlations of enzyme-linked immunosorbent assay-measured plasma and cerebrospinal fluid (CSF) apolipoproteins (apoA-I, apoC-III, apoE, and apoJ) or apolipoprotein subspecies (apoA-I with and wi...

BACKGROUND Developing measures to detect preclinical Alzheimer's Disease is vital, as prodromal stage interventions may prove more efficacious in altering the disease's trajectory. Gait changes may serve as a useful clinical heuristic that precedes cognitive decline. This study provides the first systematic investigation of gait characteristics relationship with relevant demographic, physical, ...

OBJECTIVE To explore the frequency and significance of ApoE gene polymorphisms in patients with sporadic Alzheimer's disease (AD). METHODS Single nucleotide polymorphisms of the ApoE gene were analyzed in 32 cases of AD and 26 controls, using PCR and gene sequencing. RESULTS The single nucleotide polymorphism of ApoE gene 462C/G was significantly associated with AD (P < 0.05). CONCLUSIONS...

BACKGROUND The purpose of this study was to compare apolipoprotein E ε4 (Apo E ε4) and apolipoprotein E ε2 (Apo E ε2) as predictors of cognitive and functional trajectories over 30 months. METHODS This prospective cohort study included 287 community-dwelling memory clinic patients with dementia, mild cognitive impairment, or no cognitive impairment. The Addenbrooke Cognitive Examination, Mini...

Apolipoproteins (Apo) A-I, A-II, A-IV, and E possess repeated amphipathic helical regions with the same genomic structure and are members of a multigene family that probably evolved from a common ancestral gene [1]. These apolipoproteins play pivotal roles in lipid transport and lipoprotein metabolism, and their carboxyl-terminal domain is critical for lipid binding [2]. The purpose of this com...

Atherosclerosis is a multifactorial highly-complex disease with numerous etiologies that work synergistically to promote lesion development. The ability to develop preventive and ameliorative treatments will depend on animal models that mimic the human subject metabolically and pathophysiologically and will develop lesions comparable to those in humans. The mouse is the most useful, economic, a...

It is well established that the cholesterol-transporter apolipoprotein ε (APOE) genotype is associated with the risk of developing neurodegenerative diseases. Recently, brain functional connectivity (FC) in apoE-ε4 carriers has been investigated by means of resting-state fMRI, showing a marked differentiation in several functional networks at different ages compared with carriers of other apoE ...

objectives: this study was performed to investigate the effect of ω-3 fatty acids on lipid profiles, lipoprotein (a), apolipoprotein a-1 and apolipoprotein b, fasting glucose and insulin, and insulin resistance in a group of iranian elderly subjects. methods & materials: in this clinical trial, 124 elderly residents of the kahrizakcharity foundation, aged 65 and older were divided into two inte...
